GA-1

GA-1

The Boeing GA-1 (company designation Model 10) was an armored triplane. Designed in 1919, it was powered by a pair of modified Liberty engines driving pusher propellers. The first of the Engineering Division's heavily armored GAX series (ground attack, experimental) aircraft, the ponderous airplane was intended to strafe ground troops while remaining immune to attack from the ground as well as from other enemy aircraft. Its armor resulted in an excessive five-ton weight.
